BACKGROUND OF THE INVENTION

[0001] The present invention relates to a handy battery charger forcellular phones, and more specifically, a handy battery charger tosupply power to the cellular phones by the handy charger with thebatteries in case that the usual indoor charger using alternate currentsor in vehicle is not equipped or the battery of the cellular phones isrun out to need a rapid charger.

[0002] In recent days, the cellular phones are widely used and anauxiliary battery may be equipped by the user besides the cellular phonebattery in order to prevent the battery discharge in use, and it can bereplaced with auxiliary new one. If the auxiliary battery is notequipped, the cellular phones in integral with the discharged batteryare to be recharged at the exterior charger or hands-free knit ofvehicle.

[0003] In order to continuously use the cellular phones, a person shouldkeep an auxiliary battery at all times for the cellular phones. However,there is a tendency to only use the battery in integral with thecellular phone because it causes a user inconvenience to carry anadditional auxiliary battery. Further, to carry the auxiliary batterymay cause shortcut of the recharging terminal of the auxiliary battery,resulting in discharge.

[0004] Limited use of the charger according to the place in rechargingthe cellular phone battery often brings about the battery discharge.Otherwise, the cellular phone should be in a standby state until thecharger completes recharging operation.

[0005] Since a conventional charger generally utilizes alternativecurrents, 110V˜220V, designed for indoor or public use, it becomesdifficult to recharge the battery at the outdoor place withoutalternative currents. In a vehicle, power of 12˜24V in travelling thecar is utilized to recharge the battery but this necessitates ignitionof the vehicle and the indispensable articles may be caught on insidethe car.

SUMMARY OF THE INVENTION

[0006] The present invention is derived to solve the above conventionalproblems, and has an object to provide an handy battery charger forcellular phones, wherein the dry cells are held in the charger body toreadily recharge the phone battery at any time regardless of the place.

[0007] In order to accomplish the above objects, there is provided ahandy battery charger for cellular phones, comprising: body in assemblyand disassembly for forming the cell reception within the hollow, upperand lower cases; connector with a plurality of connecting pins arrangedat the upper side of the body corresponding to the connector at thebottom side of the cellular phones, for selectively connecting to theconnector of the cellular phones to supply the output voltage of cells;a couple of resilient binding clips arranged at the opposite ends of theconnector for preventing accidental release from the connector of thecellular phones; and a plurality of positive and negative coil terminalsto arrange the cells in serial and to supply the output voltage of thecells to the connector.

[0008] Therefore, the user can take an advantage of recharging thebattery of the cellular phones by connecting the connector at the bottomside of the cellular phones to the handy battery charger of the presentinvention, thereby achieving the cellular phones to be in continuous usestate.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The handy battery charger of the present invention comprises abody 1 in assembly and disassembly for forming the cell reception 15within the hollow, upper and lower cases 11 and 12; connector 2 with aplurality of connecting pins arranged at the upper side of the body 1corresponding to the connector 51 at the bottom side of the cellularphones 5, for selectively connecting to the connector 51 of the cellularphones 5 to supply the output voltage of cells 6; a couple of resilientbinding clips 3 arranged at the opposite ends of the connector 2 forpreventing accidental release from the connector 51 of the cellularphones 5; and a plurality of positive and negative coil terminals 4 a, 4b, 4 c and 4 d to arrange the cells in serial and to supply the outputvoltage of the cells 6 to the connector 2.

[0016]FIG. 1 is a disassembled perspective view of the handy batterycharger to the cellular phones.

[0017] The body 1 is divided to detachable/attachable upper and lowercases 11 and 12 by using any thin tools to replace old cells into thecell reception 15 with the new cells 6 of 1.5V.

[0018] The cells 6 are arranged with a predetermined interval within thecell reception 15 of the body 1. The positive and negative terminals arearranged in serial by the coil terminals 4 a, 4 b, 4 c and 4 d, and forinstance, three cells 6 connected in serial be arranged to provideoutput voltage of 4.5V.

[0019] The coil terminals 4 a and 4 d arranged at the opposite ends areelectrically connected by way of insertion or soldering to the connectorpin 2 a in the connector 2 of the coil terminals 4 a, 4 b, 4 c and 4 d,and electrically connected to the power terminal from the connector 51pins of the cellular phones 5.

[0020] The cells 6, positive and negative coil terminals 4 a, 4 b, 4 cand 4 d and the connector 2 are kept in electrically and in serialconnected (FIG. 4).

[0021] In case that the battery of the cellular phone 5 is discharged,the connector 2 at the top side of the body 1 is inserted to theconnector 51 at the bottom side of the cellular phones 5, so that thecell voltage in serial connected by the positive and negative coilterminals 4 a, 4 b, 4 c and 4 d in the body 1 is supplied to theconnector 51 of the cellular phones 5 through the connector 2.

[0022] This connection enables the cellular phones 5 to be rechargeableby supplying the cell voltage to the battery of about 3.6V of thecellular phones 5 and to the circuit portion, so that the user can putthe cellular phones in desirable use while recharging the battery.

[0023] In order to prevent the body 1 from being separated from thecharger by an accidental clash or collision, a couple of resilientbinding clips 3 is arranged at the opposite ends of the connector 2 ofthe body 1. One end of the resilient binding clip 3 is inwardly bentperpendicular to the body 1 and hinged to pivot, and the free end of theresilient binding clip 3 is maintained at the opposite ends of theconnector 2.

[0024] In engagement of the connector 2 to the connector 51 of thecellular phones 5, the resilient binding clips 3 serve to ensureinsertion by hanging into the groove (not shown) at the opposite ends ofthe connector 51 of the cellular phones 5. While undesirable separationof the connector insertion is prevented, the user may readily make themseparate by hand manipulation.

[0025] The lower case 12 is configured detachable for replacement andreception of the cells. Upper portion of the body 1 is covered with acap 30 to protect the connector 2.

[0026] A couple of inserting grooves 31 is formed at the opposite endsof the body 1 to ensure the cap 30. A couple of projections 32 areformed at the cap 30 to correspond to the inserting grooves 31, so thatthe cap 30 is fixedly put on the body 1.

[0027] The cap 30 includes a connecting string 33 to the body 1, inorder to prevent the cap 30 from missing. The connector 2 is protectedby the cap 50 from contamination.

[0028] As described above, the present invention provides a handybattery charger with the cells to recharge the battery by connecting tothe connector at the bottom side of the cellular phones regardless ofthe place where the conventional battery charger generally is a indoortype using alternative currents or in a vehicle, thereby allowing theuser to use the cellular phones without falling in a turn off state dueto the battery discharge.
